The Convergence vs Alisa Black, Dark Adam and the Dragon Ball Villians

Weakness

Highly cocky

Obsessed at destroying Adam

Cell

Superhuman Physique

Absorption: This is one of Cell's more famous techniques. He uses his tail (which is concealed in his Perfect-Super Perfect forms) in order to gain all of the strength that the victim possesses. There are two methods to faciliate this technique: The first involves him stabbing the target and extract all of the organic matter of a victim, which leaves the clothing behind. The second involves him directly swallowing the person whole through his tail, holding them unconscious in his body. This is his preferred method since he also obtains the full power of those he absorbed through this method.

Regeneration

Originated from Piccolo's cells; however this was modified to be far superior to Namekian regeneration and allow Cell to survive decapitation or near obliteration.

Ki Manipulation

Telekinesis

Able to survive in Space

Summoning Cell Juniors, the seven offspring of Cell himself.

Teleportation w/ Super Perfect Cell via the Instant Transmission technique

Feats

Regenerated his upper body after it was blown off

Regenerated after blowing himself up. This explosion is powerful enough to destroy the Earth.

Completely unaffected by human weapons; including massive manmade explosives

The Cell Juniors are powerful enough to match Cell Saga Vegeta and Future Trunks

Learns Instant Transmission when he teleported with Goku near the end of the Cell Games Saga

Weakness

Can still die if all of his cells are obliterated.

Killed by Gohan's Father-Son Kamehameha.

His healing factor can temporarily burn out if he takes too much damage or pain; hence why blunt force has managed to defeat him and why Goku saw it necessary to give him a senzu bean.

Likewise his Ki can run out and needs time to recharge.

Will regurgitate any androids he previously absorbed if Cell takes too much damage. This could return Cell to a previous form as well; weakening him.

His tail cannot 'drink' the fluids of robots or non-organics. 

His tail's absorbing abilities require time to perform; meaning if Cell is interrupted then his victim can escape.

An enemy significantly more powerful than Cell can escape being 'swallowed' by his tail. 

Cocky enough to allow his enemies to rest and train for 10 days before his rematch against them.

Cell was officially Android 21 before DragonBall FighterZ introduced the new character. It's unclear if Akira simply forgot this fact.

Frieza

Frieza is of a race that can survive in the vacuum of outer space and whose transformation sequence places restriction of their full power. As he initially appeared in his first suppressed form, Frieza has a power level of 530,000. When he assumes his second form, which bares resemblance to his father, Frieza's power jumps to more than 1,000,000 and even more when he assumes his reptilian third form. In his true form, Frieza has a power level of 120,000,000 but rarely uses his full power unless pushed to his limits while slightly bulking up.
