PokéSync: Brock Harrison's Wife Poll (Patreon)

Brock's last name:  Most official sources do not give Brock a last name. However, several sources suggest that in the anime, his last name is Harrison. In the July 2006 issue of K-Zone Magazine, Eric Stuart was interviewed, and he said Brock's last name is Harrison.

The Girls!!:  There are a number of girls that could have ended up with Brock within the anime lore.  I thought I'd give you guys the chance to pick this one.  =))

Lizabeth:  Her family is a descendant of the People of the Water, while also owning and performing together for their profession in an act they called The Marina Group.  She's shown to return Brock's affections.  She would probably be a Level-5 Ranger or Gold-tier Trainer at best with having so many Pokemon for their performance.

Hey, Lizabeth is also the inheritor of an entire advanced underwater city called Samiya while having a connection with Manaphy (less as a captured Pokemon and more of a city symbol/guardian).  So, Brock could have his own city by marrying into the only living descendants xD sweet perks.

Olivia:  Alolan Grand Master, Active Elite 4 Member, Rock-type specialist.  They had some chemistry in the Anime, and she showed signs of being attracted to our former Gym Leader.

Lucy (a.k.a. Pike Queen):  A Battle Brain (High Master-tier) of the Pokemon Frontier in Hoenn (south of Sootopolis City).  She is shown to actually be one of the most susceptible females in the series to Brock's 'charms', and would very likely have become a couple with Brock if the group didn't cockblock.  >.>

Holly:  A bit older than Brock, and at first didn't want anything to do with him, but after battling with the former Gym Leader in a tag-team match, she found a spot growing in her heart.  The cute part is that she felt responsible for his loss in the following battle, and she didn't feel worthy to date him, so she left to get stronger.  Could make for a good story.  I'm leaning between Gold-tier and Platinum for her rank as a competition participant.

Autumn:  A cute red-headed maid girl that happens to have a crush on Brock!  She was a bit young when they met (Brock was more interested in her maid older sisters); although, upon a second trip to the place, perhaps Brock found the young girl had blossomed.  =))  She also is very concerned and dedicated to her Pokemon; I'm going with Silver-tier, though.

Wilhomena:  A bit of a sheltered rich Johto girl (Silver-tier Trainer) that grew to have an affection for Brock over the episode, hinting that she hoped he'd come back for her in the future.

Natalie:  While Natalie may have been too young when Brock first met her, a decent amount of time has passed, and she certainly had a crush on him.  It was revealed in a later episode that Brock still had the Berry book she gave him, too (just a helpful book, or maybe a lingering connection?).  She would be a Berry Expert and Silver-tier Trainer.

(Not a candidate) Narissa:  Only a temporary, self-conscious reaction.

(Not a candidate) Temacu:  Brock, being the smooth guy he is, swooped in, catching her before she fell into a fountain.  She asked for his hand in marriage (shocking Brock), but she was just a wedding crazed teen that ended up marrying her doctor at the end of the episode ... yeah ... her doctor xD

(Not a candidate) Professor Ivy: While I'd love to see her added to the poll, she flatly rejected him, and Brock is somewhat scared of her.  xD  Who wouldn't after all those chores she made him do.
