Serpentor

Considered to be a maniac, Serpentor is perhaps the most fearful being within cobra, not only does he has an extreme personality which adds to his mental instability, he’s also quite ambitious and intimidating, Cobra commander feared he would one day take power.

Which he did, before Cobra commander took it back.

History:

The man who would become Serpentor was born in 1970 and was one of many troops recruited into the ranks of Cobra. Though his climbing of the ranks wasn’t that bad, many members were concerned of how mentally instable Serpentor was, as he was quite cruel.

During the invasion of Cobra island, Serpentor betrayed Cobra commander and seemingly killed him, after taking his place as the new Cobra lord, he won the battle and was later seen talking to Zartan and Destro about future plans[G.I.Joe Vanguard 2 of 4]

He sent Zarana and Big Boa to Florida to find Croc master, and had a brief phone call with him at his cabin[Mystery of Croc master]He was overseeing the testing of the M.A.S.S device along with Viper when it malfunction due to Croc master teleport.

Once Croc master arrived, he interrogated him, and when he felt that he was a threat, tried to execute him twice in a row, only in his horror that they failed to even kill Croc master, despite anybody else would probably die of the wound he received[Arrival of Croc master]

Thinking that Croc master wanted to kill him, He ran to the Lab room, with Croc master in pursuit. He was more terrified when Croc master survived Viper shooting him, and caved into Croc master demand shortly afterwards[Reveal of Croc master]

He ordered the capture of the Joes while they tried to get into Nanzhao, and boasted to them about his desire to conquer the world, promising them to make them watch him win[Total failure]He was killed in a confrontation with Cobra commander.

However he did take out Old snake before he died in the confrontation[G.I.Joe Vanguard 3 of 4]
