The damage champions can only be countered by Jenos ult. If they flank you, or you leave yourself wide open, they can easily kill you. Void Grip can stop some of them from escaping. If you use Void Grip on one of them, go behind cover. Skye is the only flank that is terrible against Jenos. Just buy Illum, and use Stellar Wind to avoid her. If Skye is too close to your team, use Void Grip on her.Void Grip Torv if he is wide open. Void Grip can allow your team to easily avoid Khan's, Term's, and Nando's shields. Either use it so that they can't protect themselves, or use it so they can't protect their back lines. Raum doesn't have much range and his movement ability won't be enough to stay close to you. If he tries to run though your team, Void Grip him while he is in the middle of them. If he tries to use his movement ability to escape, Void Grip him to cancel it. If you time it right, Raum can shoot without a minigun. Lum also helps your team destroy Raum. Jenos can snipe supports with his ult. A couple of them can easily avoid it. If Grover ults, you can ult and kill him (Grover is the only support that can survive Jenos ult without maxing his hp card, so check his loadout to see if he can barely survive Jenos ult). Lex can't escape from Void Grip until next patch. After this patch, Jenos can only counter Lex by ulting him if he decides to stay in the backlines.

Flanks destroy Jenos. Stay closer to your team if you keep getting flanked. If you are in the open a lot, snipers can pick you. Ash, Term, and Ruckus can be good flanks. Be careful around Makoa, he can take you out of the backlines. Lex Will be better against Jenos next patch because he will be able to escape Void Grip without a bug (which is being patched). Vora will also be good at flanking Jenos. Jenos ult will one shot you.

Jenos buffs are strong with a lot of champions. Jenos usually needs a support that can actually heal (a few comps can work with solo heal Jenos.) If Seris gets a good ult, you can combo it with your own. I don't recommend doing this though since her ult can be avoided easily and her healing gets destroyed by Caut. Cassie ult can make it easier to hit with Jenos ult. Talus ult can do the same if he cancels it (Requires communication). Best support for Jenos is easily Corvus with Spreading Influence. He heals a lot and can give speed and lifesteal buffs. Best possible comp: Jenos, Corvus, Viktor/Vivian, Buck/Andro and Term/Inara.
