Rovuscious is known to be extremely harsh and is always determined to beat another competitor. He is also shown to be very arrogant and egotistical as he loves rubbing his success in the faces of others. When he first appeared, he mocked and bullied Mem and Zen at the New Virus Warriors Convention by showing off his new recruits and then made insults towards Mem and Zen over the fact that they have not yet won any awards and that they mistakenly selected the Noobs while he laughs at them and gloats over the seven awards that he won. This bullying caused Mem and Zen to leave with the Noobs to another room and not attend the convention feast which spared them from being poisoned food contaminated with virus by Count Venamus and allowed them to foil Venamus' plans and expose him. As a result, Mem and Zen won the recruiter of the year award while Rovu's was seen angry and jealous of Mem and Zen because they won the award and broke his streak. Despite all these flaws, Rovu did show that he was capable of caring for other people as in The Noob-i-nators 2: Save the Earth! he saves Mem and Zen from being overrun from the virus infected citizens of Cornbury and even fought alongside them.
He looks similar to Zenblock and Memnock, aside from the fact that he is red-colored, has more armor and his Battle Ball is blue.
Rovu is shown to have a huge rivalry and strained relationship with both Mem and Zen. Rovu often bullies Mem and Zen as he is arrogantly condescending towards them due to their lack of award wins. It is clear that Mem and Zen dislike Rovu for his gloating, bullying, and arrogance towards them and because of this, they desire to stand up to Rovu and prove to him that they are great virus warriors and they were able to do so by exposing Count Venamus, saving the new warrior recruits from the virus, and winning the recruiter of the year award and breaking Rovu's winning streak. Despite the fact that Mem and Zen perceive Rovu as an arrogant and egotistical bully, they are fans of the mega popular show Extreme Virus Warriors, which Rovu stars in. Rovu also saved Mem and Zen from having to go through a grueling fight with the virus infected citizens of Cornbury which they would have most likely been defeated in and he fought alongside them, which implies that Rovu, Mem, and Zen were once teammates and allies who worked together when they were young but that Rovu separated from that team after being corrupted by his own success.
- He has won at the Virus Warrior Convention and Recruiter Awards every year with 7 awards in total. However he lost the most recent one to Mem and Zen.
