With the consequence of slightly worse bulk and an unnecessarily boosted Attack stat, Exploud paired with Thundurus-T becomes a much more potent wallbreaker, sporting a massive
base 145 Special Attack. Just look at the power:
252+ SpA Choice Specs Exploud Boomburst vs. 4 HP / 252 SpD Blissey: 261-307 (40 - 47%) -- guaranteed 3HKO after Leftovers recovery
Even aside from Scrappy Boomburst, Exploud has a nice special movepool, including Focus Blast and Fire Blast for perfect coverage. It also has some nice disruptive tools in Fake Tears and Taunt if you want to go down that route.
Alternative donors:
(80/90/80/130/110/110) 15 less SpA, but much better all-around stats including Speed, and a lower Attack stat as well
(75/125/70/125/70/
115) Even faster than Latios although slightly weaker, but even more frail than Thundurus-T and has an even higher Attack stat
Alternative recipient:
Although Swellow possesses more weaknesses (notably Rock) and an inferior special movepool, it has access to something notable that Exploud doesn't: U-turn. With an Attack stat like that of Thundurus-T or Azelf (or perhaps even Latios), Swellow can use this tool to deal some respectable chip damage while keeping momentum.
In regards to support options, Swellow lacks those of Exploud, but it does have access to Roost for improved survivability, as well as Defog for hazard control if needed.

This may seem like a weird combination, but Accelgor's stat layout gives Parasect the fastest possible Spore in this OM. It also has some usable additional options in Knock Off and Giga Drain, but its special coverage is basically limited to Hidden Power.
Alternative donors:
(78/81/71/74/69/126) At the expense of 19 base Speed, Talonflame offers an Attack improvement of 11. (Plus Talonflame on its own has a tier advantage.) With the Attack improvement, it can viably run Swords Dance with either X-Scissor or Seed Bomb alongside Spore and Knock Off.
(115/115/85/90/75/100) Going further down the ladder, Entei offers +45 Attack at the expense of 45 Speed.
(105/
140/55/30/55/95) Not that it matters much, but this is the highest Attack stat that you can give to Parasect (or any other Red Pokémon for that matter). Base 95 Speed is below average, but base 140 Attack is frightening.

Apparently Exeggutor is the only Yellow Pokémon with access to Sleep Powder and therefore the fastest reliable Sleep inducer in this OM. Along with that, it gets access to Swords Dance, Wood Hammer, and Zen Headbutt for offensive options.
Alternative donor:
(65/65/60/110/95/130) While offering notably less Speed than Ninjask, Jolteon offers better stats all around and allows Exeggutor to use its usual special movepool featuring Leaf Storm, Giga Drain, and Psyshock. Sadly, though, Exeggutor does not have a boosting move for its Special Attack.

Spinda has a neat movepool consisting of Contrary Superpower among other things, and now it doesn't have to worry about having a crappy 60/60/60/60/60/60 stat distribution. Shame that Superpower is still incompatible with Baton Pass and Wish, though.
Alternative donor:
(89/
145/90/105/80/91) Stronger and faster but with slightly less bulk to offer

Speaking of improved Contrary users, how about an improved Malamar? Okay Speed, okay bulk, okay Attack...what could possibly go wrong? (Well, it still has that nasty Bug weakness, and that slight Fairy weakness as well...)
Smeargle has already been mentioned, but I'll mention its potential donors in more detail.
(65/
130/60/75/60/75) While possessing a rather low BST with no changes to Speed, this is the highest possible Attack stat that can be given to Smeargle. As mentioned, the main thing that defines Smeargle as an offensive threat is access to BellySpeed, with which it can run Spore or Dark Void for reliable sleep induction and Sucker Punch for Ghost-types.
(68/125/65/65/110/80) An alternative to Absol with less Attack but better stats all around.
(85/60/65/
135/105/100) Smeargle can also run a specially offensive set with Boomburst, but this is less effective than its physical set due to the lack of STAB priority. Note also that the only thing preventing it from being outclassed by Thundurus-T+Exploud is its access to an infinite expanse of boosting moves such as Shell Smash and Tail Glow, as well as, again, reliable sleep in Spore/Dark Void.
(100/77/77/128/128/90) An alternative to Volcarona with better bulk at the cost of offensive prowess.
(70/80/70/80/70/
110) This is the highest Speed stat that you can give to Smeargle. This means that it's the best build to use when running standard utility Smeargle with hazards and whatnot.
(85/50/95/120/115/80) Togekiss is perhaps the best that the color White has to offer in terms of bulk. Base 80 Speed isn't bad either. I can't imagine what Smeargle would want with bulk, though.
