Buck

Buck (Japanese: バク Baku) is a Pokémon trainer from Sinnoh. He is one of seven trainers who can join with the main character during an event in Pokémon Diamond and Pearl. Buck is a strong trainer from Fight Area which is close to Stark Mountain volcano, where he loves to train. Later, he can join the player in competition at Sinnoh's Battle Tower. He first appears at Stark Mountain and is part of the event required to catch Heatran. His name is derived the Japanese word for explosion (爆破 bakuha) which possibly refers to his training place, a blazing volcano. Buck's older brother is an Elite Four member, but who it is exactly remains unknown. Some speculate that it is Flint, because of his preference to Fire Types, but this, also, isn't confirmed.
