The shield’s Vortex ability is very versitile. It allows the wielder to gather a bunch of projectiles and shoot them in large bursts. It allows the user to steal/break an opponent’s weapon if it’s caught in it. It can even chop off limbs caught in the vortex with ease. If the wielder has allies, they could ask them to shoot projectiles into the shield he can use later. If the person is small enough, he can even fit them into the shield and eject them at will without killing them. If there are other Vortexes in the realm it sends you to, and you have the power to move through a space like enviorment, you can escape through other vortexes, but of course, there aren’t many vortexes, and lesser so vortexes that lead you to safety. Once I get a design for the shield, I’ll make an animation full of examples.

Honestly dude I wouldn’t give him a weapon, his shield gives him both strength and weakness. If you ever plan to fight this guy against someone you will have to balance him. He will rip CQC fighters but have troubles with range/magic users, this is where u could use your companion character to swapout the character (having both on screen will be op,tag team that shiz) your companion could be weak to melee but strong against range/magic (combat triangle) you can make some sweet combos. Imagine this, your shield dude is getting a barrage of attacks to his shield building up his (absorb/reflect ability) then at the last second he step back aims his shield to the sky, your companion then runs in jumps on shield blasting him skyward leaving the companion invinisble to damage while in the air, proceeding a counter barrage from the air. (melee fighter will be to heavy to jump or lack abilities to get that high) honestly I like your idea just don’t over do his strength, every bad a$$ has a weak spot (any story ever)
