You are no mere conduit, you're the very driving force of human evolution. You're the pinnacle of conduit potential and far more. Your body now possesses the ability to instantly adapt to any new powers you possess removing it’s negative side effects such as electrocuting yourself in water and can now gain new abilities by either absorbing massive amounts of your elements/energies, stressing your body and powers in new ways, or forcing RF energy into your body.
As a start the base abilities you gain as a conduit are enhanced by a ludicrous degree, your strength, speed, agility, stamina, durability, and basic regeneration are increased to put you as far away from prime conduits as they are from regular humans, allowing you to casually rip apart large structures and take even a 51 kiloton nuclear strike and recover in moments no worse for wear.
The beast had the incredible ability to manipulate matter and energy, capable of breaking it down and absorbing it or manipulating it for various purposes. You can perform transmutation, turning matter and energy into a different form of whatever you wish. You are now capable of performing feats such as absorbing and cleansing radiation, releasing blasts that can disintegrate most, even manipulating the structures of other beings at will to give them the conduit gene, or even something as blasé as creating clothing for yourself. Through this power you’ve also been given incredible control over the weather allowing you to create blizzards, hurricanes and even raise volcanoes.
You possess the ability to manipulate gravity to a significant degree, able to create a localized singularity to absorb all nearby matter and energy or nullify its effects. You can choose to exclude some from the effects of your powers.
Perhaps The Beast’s most well known ability is his power to alter his own shape and size at will. You’ll start off with the instinctive skill to turn yourself into a giant lava-incarnate capable of toppling skyscrapers simply by moving, as well as turning yourself into a singularity to absorb massive amounts of matter and energy and nullify attacks against yourself. This particular power is also the reason behind your incredible regeneration, allowing you to absorb surrounding material to reform yourself from even a single atom. You are by no means limited to these forms, and can take a variety that best suits your needs.
As for his second most well known ability, that would be his ability to manipulate fire. You're now a pyrokinetic on a terrifying scale, capable of leveling cities and sinking ocean liners in a single blast. You also possess incredible precision, capable of using it to do nothing more than heating a homeless man in the middle of a blizzard on the other side of the city if you're feeling charitable. All your other elements are enhanced to the same degree of power and precision.
And finally the very ability that made The Beast an absolute threat to all of humanity as a whole, the manipulation of RF energy. You now naturally generate massive amounts of RF energy, which can be used in a number of ways. This passive generation will slowly increase your power over time. The most notorious use is that you can generate a massive and powerful blast that activates any nearby conduits, greatly amplifying your own power, while simultaneously killing any nearby humans. This blast can be powerful enough to lay waste to the entire east coast, wiping entire cities off the map or even split the moon. Manipulation of RF energy allows you to manipulate the powers of other conduits making you capable of enhancing them, negating or turning off their powers, or even granting them new ones. You may instead of utilizing a blast, use the passively generated RF energy to awaken any new conduits. The energy you produce doesn’t have any of the negative effects shown in the series, unless you intentionally use it for that.
Alongside his major abilities you are granted the following powers of telepathy, allowing you to read and communicate directly with others through their mind even over massive distances, teleportation; allowing you to instantly travel large or short distances in the blink of an eye, as well as flight and levitation. As a bonus you are also granted the powers of all the other conduits shown in the series, with their elements being enhanced to be on par with The Beast’s fire, and the rest of their other abilities rising at a similar scale. You’ll also get Cole’s and Delsin, both good and evil versions, skills and experience to go with this. Your power also requires no more effort on your part than blinking, your power simply doing what you’d like it do.
