A wacky arcade Beat 'em Up made by Irem in 1993. In this game, four baseball-themed ninja superheroes are hired by the commissioner of a baseball museum to retrieve a golden statue of Babe Ruth, as well as the statue's matching golden baseball equipment, when they're stolen by the evil Jado syndicate. They must travel all over the major cities of the USA to recover the pieces and assemble the statue so it can be returned safely.A good game, underrated, and sometimes MAME can't quite handle it.Has nothing to do with a certain Caped Crusader playing baseball.
Animate Inanimate Object: Several of the Mooks you face are baseballs, baseball bats, baseball gloves, cards, and there's also the floating stuff that the poltergest attacks you with.
As for bosses, The Defending Slot, the Ghost Buffalo and technically, the Final Boss.
A.I. Breaker: The Final Boss is pretty hard if you try to get up close to him, because of his tornado swing move that does a lot of damage and has very good range and priority. If you stay far from him though, he'll use a baseball slide which is very easy to counter via your normal attack (don't stay too far, or else he'll whip out the electrified bat).
Flash of Pain: The player characters suffer seizure times of turning red when they're low enough on healthnote akin to the boss characters from most Konami beat 'em ups... until they lose a life.
Flunky Boss: Mad Lax, who drops a bunch of crocodile car enemies even now and then.
Makeshift Villain will summon the dogs with Tommy-guns for about 3/4 of the fight.
Giving Up the Ghost: Enemies may sometimes die like this, with music from Fur Elise for some reason.
The Gunslinger: The Tommy-gun armed dogs are a Type B and C: The Vaporizer and The Woo respectively. They shoot like crazy and have a rolling back jump where they fire in the air giving them a brief float.
Helpful Mook: The burger enemies in the Texas stage. They can initially hurt you, but as soon as you hit them once, their eyes fall off, and then they become a food item that restores a good amount of health. Best of all, they appear in large numbers.
They player characters count as well, being ninja baseball players.
One-Hit Kill: For some reason, if properly defeated (they like to run away), the blue submarine-carrying foes drop their skeletons, which can kill almost all mooks in a single throw (only ones that survive it seem to be the octopi, if they're still carrying their hats).
One-Winged Angel: The statue of Babe Ruth, after the commissioner takes it from the ninjas.
Personal Space Invader: Quite a number of enemies have a very annoying grab move, such as the mini walking bombs and the pink dog mafia.
Press X to Not Die/Smashing Survival: An early arcade example. There are certain enemies can grab you, and you need to either shake the joystick back and forth or press the attack button rapidly.
Recovery Attack: Both the players (in their case, a home-run swing) as well as the bosses (when getting up after a knockdown) have it.
Revenge: Captain Jose, after discovering the commissioner was Evil All Along and defeating the evil robot he made out of the Babe Ruth statue, hits him with his bat so hard that he ends up crashing into the moon.
Shows Damage: Rare for a Beat-Em-Up game. Most of the bosses have parts that drop off as soon as they take enough damage. In one case (Mechanical Alligator), his tail drops off and starts to attack you!
Stout Strength: Beanball Roger is the heaviest of the bunch, and his body is basically a perfect sphere with arms and legs. He's also the strongest, and likes to flex his muscles like a bodybuilder as he walks.
Trademark Favorite Food: Beanball Roger sure loves to imagine curry rice in his idle animations, and in fact is served on by Stick Straw during the cut scenes.
Underground Monkey: While the enemy variety is large there are some palette swaps that do different attacks. The playing cards with arm cannons have unique attacks: The orange cards has charge attack, the yellow cards shoots flames, the green cards open themselves up to shoots a giant metal fist, and the blue ones spin like a tornado.
