Lol, thats a goku level entrance right there. Enter the fight nonchalantly after people are beaten to shit and about to die. As they insult you and talk about how weak you are compared to them and how hopeless it still is you ignore them and converse with your injured friends. They get angry and attack you in the back but you teleport away to talk to a different friend to give them a senzu bean and keep acting like the enemies dont exist.
