Your blood is now a different colour...

[SnakeoilSage]

Double-post, pardon me.

 

[Custard_Angel]

I die very quickly because the resonance present in haemoglobin has now broken down, iron no longer chelates to its position in the crown structure, oxygen is no longer coordinated to the blood and my body, now with no method of transporting oxygen, shuts down and I die after every single organ and organelle chokes to death simultaneously.

I'll keep my red blood where it is, thank you.

 

[Bravo 21]

my blood whould be glowing red, so like normal blood, but if i get cut, it will be rather clearly visible. i will be able to teleport, and move inhumanly fast. I shall be chaotic good. for certain values of good.

 

[Todas]

White, and I can fly/hover for however long I want.
I shall be neutral because flight is completely useless in most cases.

 

[SextusMaximus]

My blood is now green and can throw up all over myself on command.

brilliant!

 

[walrusaurus]

electric purple (its a real color look it up) And i'm going ot go with telepathic empathy. both ways.

 

[phantasmalWordsmith]

My blood turns a different shade of red (I like red), my power is healing (wolverine style)

 

[BabyRaptor]

Um...White. White sounds nifty.

I want the ability to teleport. 30 seconds sounds sufficiently long to get a picture of where I want to go in my mind and cast a spell.

 

[Russian_Assassin]

My blood is Black. My power is that I can control all of my blood (cut my arm, let some spill, shape it into a blade-like weapon that cuts through anything, for example) and I can regenerate it almost instantly.

 

[Lizardon]

My blood is periwinkle and I have the power to explain to people what periwinkle looks like.

 

[Resonantscythe]

Purple, gravity manipulation to the point that I can increase a lump of coal's own gravity to compress it into a diamond, reverse gravity and increase it to shoot someone into the sky, or slam things into each other at bone-shattering speeds.

 

[Chaosbo1]

my blood would be white like milk and my powers are extremely heathy and extremely strong bones unlike wolverine my bones are not indestructible and i dont heal super fast. My one would be the ability to adapt and make myself stronger though experiences

 

[JokerCrowe]

My blood is now silver and I can extremely fast for the short burst.

I think you accidentally your verb.
But I'm gonna guess you meant "run".

My blood is now black and I (for short ammounts of time) have extreme strength and toughness. It also turns my eyes black, which is pretty sweet. ;D

 

[Dinosaur_Face]

my blood is black and it gives me the power to control fluids

 

[similar.squirrel]

My blood is clear like water and gives me the ability to breathe underwater and swim as fast as a dolphin

In 30 second bursts, with a 40 second cooldown.

I would pay to watch that.

OT: Green, ability to photosynthesize. I would save money on food and never get too tired. I guess that'd be pretty awesome. Although I'd probably bleed to death quite fast due to the novelty factor of watching myself bleed to death.

 

[tthor]

my blood is now plaid, giving me the ability to instantly grow a retractable beard. Boo ya

 

[The Funslinger]

My blood is... a slightly lighter shade of red, and I have the power of above average decorative tastes.

This is brilliant! Within two years, the world's metrosexual community will be your command!

OT:

Octarine. I have the ability to use magic, which tires me out. (In keeping with the OP's limit)

Soul Eater fan?

 

[torylva]

My blood is largly red, but with a hint of orange.
and my power is that i am invisible until someone has me in their sightfield, uncluding my own
