The Jamaican returned to form with a flashy 38-ball 77, laced with seven massive sixes to help RCB reach 213/2 before leg-spinner Yuzvendra Chahal's 3/31 restricted the hosts to 192/7.
Gayle, who also became the first T20 batsman on Tuesday to reach the 10,000-run landmark, said it could not have come at a better time than this.
"I like that name (UniverseBoss). He's back. Even better to be back in the field. Fans want to watch Chris Gayle, it's been fantastic," he said after being adjudged the Man of the Match.
"It all depends on how you feel, determination is important. Its a special occasion to reach 10,000 runs."
Commenting on his change of stance while taking guard, the 37-year-old said: "A lot of guys spoke to me about my stance. Even Shaun Pollock spoke to me about my stance. You're never too old to learn. People still looking out for Chris Gayle."
"The UniverseBoss is still here and alive."
Elated at the performance of his side, RCB skipper Virat Kohli said: "Happy to get those two points. People told me it's just one run, but I won't change my attitude, I've played my cricket like that."
"Chris took his opportunity beautifully, with his kind of batting, it allows me to bat through the innings, and I can chip my way out. We thought we were 30 runs above par."
Hailing the young spin duo of Pawan Negi and Chahal, the 28-year-old said: "Negi was outstanding, very brave, not getting scared. Not many people believed in his abilities. Chahal is not scared, his biggest plus point is he always wants to take wickets."
