Blue (real name Krios MacBerg) is one of the 4 members who started off TK (now we have all 4; Red, Black, Green and Blue), who is a slave to the elemental war.

Blue is the son of Reynold MacBerg, the main commander of the Icicle army, who was used for one main experiment, the Brrrzerker Serum, its a type of serum that would let out the primal rage of any Icicle and make them into an unstoppable beast…

problem is that when it was used on Blue the serum worked, but a little too well, Blue proceeded to kill everyone in that room and even kill his own brother in the blind rage that the serum gave… the serum was luckily never used again, and Blue now lives his days as a beast.

he found a way to calm himself down and to be able to speak, so he was more tame, even though he was huge, he was the most efficient assassin in the entire militia, and then Red found him and told him to come onto his team, at first he declined, but then he gave it a little thinking and agreed, as long as he could go back to the war whenever he wanted.

he doesnt go back to the war anymore…
