History YMMV / Junkworld

* Urban Stompers are powerful bulldozer constructs that exclusively use a powerful area attack and come in great numbers. On death, they drop two Rubble Things that can give Scrap Recyclers even more opportunities to activate their ability.

** Frenzy Vermins may be unimpressive to some, but when other enmey dies near them, they become overwhelmed with rage and turn into Berserker Vermin, much quicker and stronger than before. It is temporary, but they can maul a lot of soldiers while it lasts.

** Vehicle units from the Wasteland. All 3 are unblockable, Motorcycles can speed past your defenses, Smoke Runner can make towers miss and Junk Carrier buffs other units with extra health. All 3 are somewhat easy to kill, but they can be reasons for leanings and life losses where you might not expect.

** Wasteland Rat and it's counterparts are like Worgs, quick but squishy, but even they can slip through if you're distracted by other foes. Krittlings crank it to eleven due to not only having these traits, but also being mass produced by Vermincharges and Gutterballs, Underground's DemonicSpiders.
** Bloating Frogs. ActionBomb at its finest, they explode, dealing area damage and leaving behind damaging sludge. They can be killed well before they reach your units, but can be of annoyance should they do.
** Order Scientist. He might be a simple melee attacker, but he can launch syringes to give his allies regeneration and damage buff, really upping the ante if left unchecked.
** Rubble Thing. They come in great numbers and may be killed relatively easily, leaving behind a floating junk piece that will turn back into a Rubble Thing. These junk pieces, however, are a key to Scrap Recyclers evolving into a stronger form, allowing them many chances to do so.
** Flying Sentinel may be squishy flier, but if it reaches any of your towers, it will envelop them in electrified tentacles and temporarily remove them from combat. Especially dangerous when the other dangerous foes are also present.
** Order Ghosts. They have invisibility cloaking device that makes them untargetable, great melee damage and micro grenades, allowing them to greatly disrupt your choke points.
** Order Scouts, big time. For a weak flying enemy, they only appear in late levels of final world, but for a good reason. They may be weak in health, but the second they spot any Scavenger, they send an alert for backup and two Order Juggernauts drop in to wreck your defense. And they can keep doing it as long as they encounter Scavengers, flooding your defense with hulking brutes.
** Diggarz. Imagine that Quarry Worker from Vengeance, but stronger and with more underground time. You need to counter them fast if you want those three stars.
** Whiskeletons. They're not that hard to kill, but they can suddenly appear in the middle of the path or even past your defenses, and in great numbers too. Exemplified in final battle where they spawn en masse from the graveyard whenever your unit dies.
** Screechsnouts and Darkgazers are literal case. They stun towers and enemies respectively, being a much more annoying version of Screecher Bat from Kingdom Rush.

** Screechsnout and Duskgazer combo. The first stuns towers, the second stuns units. Bring these two together and the Kritt army is unstoppable.

** Gutterballs in the Underground campaign are Krittlings rolling on a huge spiked metal ball. They have a ton of armored health but low HP, move ''very quickly'', and cannot be blocked or slowed by your troops, instead just running through them for damage. The fun doesn't end when they die, for the ball [[AsteroidsMonster releases three Krittlings]] which can run past to the exit if you lack firepower or defenses.

* CompleteMonster: [[BigBad Hadron]], the leader of the totalitaristic order. He is a ruthless dictator who controls his army with an iron fist and intends to spread his rule beyond the territory of the mountains where the Order Base is. Beginning with experimentation in mind control, he has created Mad Esper and WiFi Babies, experimenting on and torturing them. When Esper went rogue and escaped, he fled to a city and imbued it with his powers, creating Psychopolis and making Hadron an indirect instigator of it's current state. After finally perfecting it, he has captured a ton of survivors he brainwashed through the use of mind control technology, forcing them to become perfect soldiers for his army. He ordered his scientists to conduct a ton of cruel experiments that, in conjunction with radiation, resulted in creation of tons of nuclear mutants, many of which used to be the same survivors, eventually combining these mutants with machinery to create cyborg killers. The nuclear leftovers from experiments resulted in further corruption of swamps, mutating even the wildlife within. He later recruited the Junkers to further abduct even more people for his army, which belonged to the Scavengers, further enforcing the conflict between two sides. Hadron then sicced the brainwashed army on Scavengers once they began to interfere with his plans as they made an effort to save the kidnapped, resulting in many casualties from both sides, his own troops dying in thousands for his world domination ideas in war they were sent to against their will. Once Scavengers finally confronted Hadron at his lair, he showed no remorse for his actions, only seeing them as new recruits and then smugly siccing one more batch of soldiers on resistance before joining them in a gigantic mecha he uses to mercilessly turn many Scavengers to the ashes. Every single survivor is happy when he finally meets his karmic end, blowing up in his mecha, his control over survivors and totalitaristic reign finally over.
