- There are a lot of enemies that are based off of animals, including the Mavericks (read: Robot Masters). It can often get to ridiculous levels. One of the biggest examples is Sting Chameleon's stage in X1, that had robot woodpeckers pick out robot caterpillars out of robot trees to attack our robot protagonist...
- Layer is so obviously in love with Zero, but the entire thing just flies over his head at Mach 1. He's so clueless it's almost adorable.
- The 4Koma strips, while non-canon, are nothing but a string of hilarity. Highlights include X's Cloudcuckoolander moments and Alia being a mildly abusive Team Mom.
- Other highlights include:Axl: But the real reason I left was my copy ability.Zero: [stares]Axl: Uh, just promise me you won't ask me to change into Alia or anything...Zero: [rapidly turns away] Like I'd do that.
- And then they made a fanart showing Axl doing exactly that.
- It is worth noting that roughly 75% of these consist of Take Thats towards X7.
- Other highlights include:
- Hitting bosses with certain attacks in X1-4 causes some funny things to happen.
- Like hitting Split Mushroom with the Lighting Web or Zero's Raijingeki.
- Use Twin Slasher to cut the web that Web Spider's hanging from and he'll fall to the ground with a splat and a hilarious yelp of pain.
- Hit Flame Mammoth with the Boomerang Cutter enough times and you'll chop off his trunk, not only disabling one of his attacks but making him look silly as well.
- The Military Train stage in Mega Man X4 has the Repliforce mooks attempt to stop X or Zero by throwing grenades at the train couplings, destroying them and creating a Bottomless Pit that the player quickly needs to dash-jump across. The first mook who does this stands a bit too close and falls into the pit he created (the second and third are smart enough to run away).
- The boss Mavericks being named after members of Guns N' Roses in the US version of Mega Man X5.
- Mega Man X4: X goes in to fight Split Mushroom, who says he's under orders to destroy him. When X demands to know whose orders it is, Mushroom replies "Take a wild guess."
- Getting the Shoryuken in Mega Man X2.Dr. Light: "Wow! You're so cool! I'm not worthy! I'm not worthy!"
- In X8, when Vile shows up for the first time since X3, X and Zero immediately ready their weapons, while Axl gives them an utterly confused look as if begging for an Infodump.
- Running into a searchlight in Dark Mantis' stage in X8 will lock you in a room with guard Reploids, who spawn endlessly. Kill their leader, however, and any Reploids left alive will charge off the platform to get away from you.
- In the same stage, Axl can trick a sleeping guard Reploid into opening the way to an electrical generator. After that, the Reploid will go right back to sleep no matter what you do, up to and including setting him on fire.
- Flame Hyenard's "BURN! BURN! BURN TO THE GROUND!" may be incredibly irritating, but it is also pretty hilarious.
- In Soldier Stonekongs level, you get the feet parts for the Glide Armor. The funny part is that Dr. Light apparently thought that someone could use a glide for evil.
- The brain-breaking implication that Bit or Byte on their own can still form a combined form of both of them if you managed to kill one of them in X3 before reaching the Doppler stage where they fuse together into Godkarmachine. Whaaaa???
- When you reach the Light Capsule containing the Hadoken ability in X1, you can see the Dr. Light hologram dressed up as Ryu.
- Even better, every time X launches one, he uses Ryu's voice clip pitched and sped up, making it sound like a midget firing off Hadokens.
- In the challenge mode, finishing off the enemy units at the right time can lead to some amusing imagery. For instance, here Iris looks like she's engaged in team-killing.
- The official Mega Man twitter account had a little fun with the "nature is healing" meme which resulted from the 2020 COVID-19 Pandemic with this tweet stating that the wild Mavericks were finally returning to their natural habitats. After showing things like Sting Chameleon in the jungle, the final image is a picture of Tornado Tonion in a dumpster.
- Some of the Achievement names in the legacy collections warrant a chuckle.
- The series lampshades it's Hijacked by Ganon Status with every final boss achievements being some variation of the same phrase. "It's Over". (X1) "It's Really Over" (X2), "It's Over.. Right?" (X3), "It's Defiantly Over" (X4), "Alright It's Over" (X5), "I'm Sure It's Over This Time" (X6), "It Has to be Over Now" (X7) and finally "It's Over, Once and For All" (X8).
