You know something I find odd that the MC hasn't done yet (or at least I can't recall him doing so) is using his tails/tentacles to entrap an enemy or group of enemies.
Lots of potential there time for me to set da scene:
MC just standing around having a horde of tails/tentacles all around the area unseen (on some Ella shit..I do recall the MC using tentacles to learn what his foes are doin)...a group of goons (or 1 powerful foe) shows up and MC just traps em in his horde of hidden tails/tentacles.
MC could weigh them all down by makin em heavy asf or toss on thorns that are leaking a poison or even a muscle paralyzer.
If you wanna go the horny route add a buncha dicks to em I guess...need to do that with Cole.
I doubt this would work against stronger enemies and would be quite consuming energy wise but with time he could just spam this restraint on lower level foes.
I just tossed this out here cause the MC is well often surrounded/completely outnumbered and this could offer a good way to level the field (in a good boi or...more lethal means).
I think that we haven't seen such use because MC tends to fight a lot of 1v1 skirmishes. However he is very tricksy with his tentacles.
1) He used a burrowing tentacle to pull his target in the ground. (Light monster)
2) He likes to draw attention with his body and leave a tentacle for backstabbing. (Danica, Evolved Michael)
3) He can trap his target in his tail and flood it with meat (Cole, Evolved Tiffany)
4) He can create a leathery field to draw memories from his opponents (Simulation against Tiffany)
5) He can use memories to understand tactics and allow his tails to mess with a squad of enemies on their own. (Against SIN)
6) He can use his extra hands to throw projectiles. Usually rocks but they can also be suppressing ordinance (Training against Minyak)
7) He can use his stone armor and special weapons to flood enemies with memories and throw them into a frenzy (Against monster Deryl)
I think the more we see MC taking part in group battles, he will start employing more crowd control tricks. MC creating a poison + memory manipulation field would be awesome.
Edit: I know that MC favors flying, but burrowing is an extremely potent ability. It obstructs vision, gives an extra layer of protection, makes attacks harder to see/predict and allows him to pull his targets into the ground where he can make great use of his mantis stuff. Ella showed how overpowered burrowing can be for a shapeshifter, and she didn't really make that great use out of it.
