[@Rune_Alchemist] Most of it is good. There aren't any actual WEAKNESSES cited though. The first one is formulated as if it's more of a strength or slight limitation than anything else. The sudden loud noises seems to be irrelevant in a fight as well, considering she'll be spamming sounds all the time. Seems only efficient as a one trick pony sucker punch. 

As is, she doesn't seem to have much of a weakness. Well actually, wouldn't her powers be severely weakened in water, or even when exposed to violent wind currents? Would make more tangible weaknesses that make sense. 

[@silvermist1116] There's nothing inherently wrong with your character. Though I don't think she'll be seeing demons in this universe. Seeing dead people though? Go for it. 

Fix that pic. 

Is she a girl though? As in does she have a vagina or is she completely absent of any genitals? If she pulls a 'I identify as x gender' though, she'll be in for a treat considering the rather grumpy/snarky cast.

[@Keksalot] Alright, let's fix the narrative real quick: There have been multiple 'versions' of this creepy rascal, and this one technically never escaped. It CAN have certain memories of such events, but the current specimen is barely a second old (the age second is generally for humans, to determine their biological age, they're all newborns however). 

I think it's common sense that I say NO to an insta-SBOOOM on a living being. It essentially makes him unstoppable to those unprepared.

Anyway, I do like his ability, but it does need a little more work in the weakness department. First off, the Kyptonite weakness, while good to know, is not only too specific (and scarce given the characters aren't exactly loaded with resources) but also barely relevant considering how open ended and lethal this guy is. For this 'weakness' to work, all matter he could potentially employ as a weapon would have to be at least merged with lead or osmium. That's ... Never going to happen. 

So now we have a teleporter, meaning he can essentially dodge anything, with Accelerator's power, which is widely regarded as absurdly OP. Now of course, everyone has the potential to be OP here, my character being a prime example. But I highly suggest you tone down the power levels here. Give a cooldown for teleports and quite prominent blacklashes. 

Also yes he's edgy, so 'Wake me up inside' must be his theme. 

Honestly, I don't want you to change his power, or his design, it's really cool even if it derives from what he initially expected. But as it is now, it's wayyyy too much. Even unlimited teleportation alone can prove to be too OP at times.
