Boombox is a chill phighter, who has a little care for Phights; like when he mentions 'No time for coffee!' when in The Iron Cafe. Boombox seems to both like being a party animal while also taking some time to relax. Boombox enjoys to make friends, and enjoys being with others than being by himself, he is very positive towards his friends, however he can end up trying a little too hard to make friends; as seen with his interactions with Biograft, Banhammer, Medkit and Hyperlaser on certain occasions, hinting he can be seen as annoying. It is difficult to make him angry.[1] Boombox is interested in other phighters’ music tastes, usually asking all them about it, and despite Subspace's taste being 'The screams of my victims!!'; Boombox is still interested by it nonetheless, however gets bad vibes from them for it.
