Brief description of concept: rubber currently only has one gear 4 ability,despite 3 being shown before gear 5 shows up,so i thought up ways that tankman gear 4 and snakeman gear 4 could be implemented,and how they could tie into getting gear 5. boundman is already in the game,so we'll skip that one.
Gear 4:tankman: this one is difficult since it was only shown at a giant size technically speaking,but i did think of a way this one could work. basically,tankman would be something of a defensive manuever,with it depleting twice as much stamina as the original,but making attacks that aren't above a certain percent of hp removal incapable of hitting. this one would also allow the user to roll into enemies as an attack,dealing massive damage. this would be obtained through a raid involving charlotte cracker(the person it was first shown off against),and would drop at a 10% rate due to the nature of the ability not being as interesting as boundman or snakeman. this one would also appear as a incredibly bloated version of boundman. and speaking of snakeman
Gear 4:snakeman: this one would be similar to boundman in that it is an offensive one,but with much,much more range on abilities. for this one,you could not be in boundman,and would instead select it directly from the original menu. this one wouldn't drain as much stamina,but would have more trouble dealing with enemies up close.
Example for appearance:
Jet serpent cannon: the user would twist back their arm before sending it flying forwards,rebounding several times before appearing at the spot the mouse is positioned at,hitting the opponent with incredible force that knocks them back.
Twin serpent cannon: the user would retract their arms before sending both at their opponent,attempting to pincer them. if both attacks hit,the impact would cause the opponent to take massive damage and also would blur the opponents screen for a few seconds.
Flight: same as boundman's,but can be canceled into jet serpent cannon or twin serpent cannon,and also moves faster.
King cobra:the user winds up their fist,enlarging it at the same time and then fires it off,with it rebounding a ton of times before hitting the opponent and dealing multiple hits,knocking them very far away. this ability could be wound up for longer,which would result in stronger hits and more knockback. the impact site of the opponent would also result in an aoe stun.
Snakeman would be obtained via candy raid with a 1% chance
