boss ideas that will drive people insane pls

a hydra that has a 1/5 chance to regen some hp when you hit him and he can knock you back with a stomp

and breath fire also he has 3 heads so to kill him you need to get rid of all three heads i can't think of any more attks but thats my idea it will probably drive people insane

That hydra could also regen a head if its not killed in time like in the myths.

Another dragon?

A tank sort of robot with a big cannon and two side miniguns that 4 has phases:

The Tank Phase: this would be when it takes less damage but its biggest cannon has not yet been extended.

The Speed Phase: here the tank loses its outer shell and is weakened but its fast with the big cannon still not out.

The Stationary Phase: the tank loses mobility but the cannon is out and dangerous.

The End Phase: the tank goes through a last ditch attempt to destroy its enemy by exploding in a huge fire ball.

The drops could be used to make a mini tank and a cannon.

a ducc mutant that shoots beams

maybe a  japanese shogun

it could call in samurai and ninja reinforcments, and at the end could turn in to a Dragon like TLOZ TOTK

drops could be his flag which could be used to summon a samurai or ninja, and his katana which could be enchanted :)
