This is how Ryan and the gang recruit the Combaticons goes in Bumblebee's Bot Force.
Jet-Vac: Ok, Ryan. What are we going to get?
Ryan F-Freeman: The Combaticons.
Pop Fizz: Why the Combaticons, Ryan? Are they heroes?
Crash Bandicoot: I think they can protect Twilight from Thunderwing.
Ryan F-Freeman: That's right. Back in To Cybertron and Back Again, they helped Starlight. It's not like a plane would fly from the sky and turn into a robot.
[Crash saw a jet fly past and transforms into a robot, landing on it's feet]
Sci-Ryan: Whoa! Is that a... a...?
Emmet: He was about to say "swan" but ok.
Sci-Ryan: Hello there. I'm Ryan F-Freeman of Crystal Prep. And you are?
Blast Off: Name's Blast Off.
[They all arrive at the Combaticon base]
Onslaught: What do you want?
Sci-Ryan: We need your help because Sunvix is here to take over this world.
Onslaught: And what do you want us to do?
Crash Bandicoot: I think Twilight needs a bodyguard. And how did you did this combining thing?
Onslaught: I'll show you. Combaticons, combine into Bruticus!
Crash Bandicoot: Whoa.
Bruticus: So about this bodyguard thing.
Evil Ryan: We need her safe for Ryan and us.
Bruticus: From who and why?
Ryan F-Freeman: I need you to protect Twilight from any bad guy at all cost. From Thunderwing and Unicron.
Bruticus: Why do they want Twilight?
Adviser Sci-Ryan: Because Thunderwing is trying to get Twilight onto his side, Bruticus.
Bruticus: Since when did Thunderwing started wanting to get Twilight on his side?
Ryan F-Freeman: Ever since I fought him and found out some info.
