Well, The Beast can give and improve the powers of conduits, which he does to Cole before giving Cole all of his powers as well. His ray sphere blasts also boost his own powers, since he absorbs the life energy of everyone within the radius and redistributes it to all conduits (including himself, and the closer to the blast, the larger a share of energy you get).
Given Cole's how he is from like, the equivalent of one historic district of New York worth of lives taken into him from one ray sphere blast (followed up by blast cores that accelerated him more), The Beast is pretty likely monstrous since he triggered ray sphere blasts in more or less every city along the eastern coast, all the way to Louisiana, all of which had him at the center.
And then there's future Cole (Kessler) to take into account to. Given Cole's acceleration (one or two ray sphere blasts + blast cores) and Beast's power to unlock a conduit's powers, by all means he should have unlocked Kessler's powers by the end. Makes him even faster, since Kessler was capable of turning his entire body into electricity to cover distances instantly. Also had the wonky time travel power.
