Team Nice Dynamite is a team created by Michael Jones and Gavin Free in Let's Play Minecraft - Episode 29 - The Walls. It combines Gavin's "nice" attitude compared to Michael's rather "explosive" angry personality. Michael is the one who came up with it. When it comes to completing tasks in both Achievement Hunter and Rooster Teeth projects Gavin is usually the cool headed idiot messing around while Michael is very uptight and competitive, often sarcastically but amicably berating, insulting and condemning Gavin for his foolishness jerking off with foul mouthed but good natured jabs, although when the crucial moment comes, they realize their friendship and teamwork is more important and choose what's right over their selfishness and bickering. Michael and Gavin also made a Let's Build in Minecraft where they made a Team Nice Dynamite Secret Room. They made a part one and part two.
In various Let's Plays, whenever the two are paired together they tend to go by their team name.
Both Michael and Gavin voice characters in RWBY and RWBY Chibi. Michael voices Sun Wukong, a Faunus stowaway who's been a recurring secondary character since Volume 1. Sun ironically has a love affair with Blake Belladonna (voice of Arryn Zech) rather than Ruby Rose (voice of his wife Lindsay Jones), though it might be because Blake is a Faunus like Sun (even though Ruby is also a team leader like Sun). Gavin voices Scarlet David (whose surname is Gavin's middle name), a guest character (and one of Sun's teammates) who appears since Volume 3. Their larger 'Team Nice Kerry' teammate Kerry Shawcross is also of Sun (Michael) and Scarlet (Gavin)'s team, as Neptune.
Michael and Gavin have also collaborated very frequently in other Rooster Teeth projects outside of Achievement Hunter's projects (Play Pals, Let's Watch, Rage Quit, The Off Topic Podcast, Shenanigans, VS, GO! and AHWU). These include (but not limited to) Live action productions (Short comedy films, Sketch comedy skits, commercials, behind the scenes, murder-mystery, sci-if and more) such as Rooster Teeth Shorts, Immersion, Million Dollars, But..., Lazer Team and Lazer Team 2, Ten Little Roosters, The Eleven Little Roosters, RT Life, RT Docs (Let's Play Live: The Documentary) in addition to animated cartoons such as RWBY, Red vs. Blue, and X-Ray and Vav, as well as podcasts such as The RT Podcast. This bromance gave them the nickname "Mavin", which ended up being the name of the dual-personality main villain of Eleven Little Roosters.
Ryan Haywood was temporarily a member of Team Nice Dynamite during EXTREME, as he was playing on Michael's account after a previous Let's Play is said to have 'caught up to him' making his own account unusable. Like Michael, Ryan also voices a recurring secondary character in RWBY and RWBY Chibi: Beacon instructor Professor Peter Port, who like Ryan in Minecraft tends to capture native creatures and hold them in various containment structures (though for Port it's for a combination of keeping the innocent populace safe and helping his students - and transfers such as Michael and Gavin's team - train, as Port captures the extremely dangerous Grimm whereas Ryan captures harmless animals).
Team Nice Dynamite is one half of the Criminal Masterminds team. The other half is The Battle Buddies. During the Fleeca Job, Team Nice Dynamite teamed up on one run while the Battle Buddies did one of their own; Gavin inadvertently set the job's first set-up on Normal difficulty instead of the hard required by Criminal Masterminds. Because it was discovered in the very first of the challenge's 26 missions the team was not slowed down by a need to re-do any missions. The team re-formed for Halo Reach LASO, where they temporarily inducted Jorge of Noble Team as a member (they had taken control of a flatbed truck that Jorge climbed onto the back of to serve as their turret).
