Brock/Takeshi is, to date, Ash's longest-standing (human) travelling companion by a wide margin, having travelled with him for a grand total of four regions. Within that time what kind of impact did he have on you and how much did he bring to the show as a character? Did he benefit from being a main character for as long as he was, or did he outstay his welcome for you? How successful were the writers in adapting him to the dynamics of three different main character groupings? Was his interest in being a Pokemon Breeder (ultimately a Pokemon doctor) explored and expanded on sufficiently? Debate the merits of the character and whatever impressions he left on you here.
