This is MeltX4! he is a hybrid of XT4 and Meltdown. After the defeat of Fire Lord, Meltdown and XT4 somehow combined, (no one knows how write your suggestions in the comments) threatening everything near them. the HF SpecOps team was sent to help. Ashidon was the best for the job (seperate Moc) as always comment a lot, like a lot and give name suggestions and let the pics do the talking, i will explain the things that you dont understand in the comments :D HAPPY MOCING!

I think that was just sarcasm. It does seem to have some sort of messy style thanks to that twisted tube contraption.
the tube is supposed to "connect" the "canister" with the acid bullets to the gun, it is kinda messy, but you have to admit that(altough you probably put more work into him than I into MeltX4) Quatros Forest Titan is a lot more messy :/
