Here's an idea for a character class. It is incomplete, but the general idea is there.
Edit: Class is finished.
[sblock=Bestial Champion]While the druids command the raw powers of nature and the rangers seem to bond with the land itself, the bestial champions form a link to all natural creatures. Though bestial champions may come from all walks of life, they are found most commonly among those raised in wild lands where the link between man and animal is more natural. They are renowned throughout the world for their skill in animal handling and taming, as well as their cunning at slaying more dangerous creatures.

Bestial Aspect 1/day (Ex): At 1st level a bestial champion may gain a +2 bonus to any physical ability score for a number of rounds equal to 3 + his Con modifier (minimum 1 round) as a swift action. If he improves his Constitution score, he uses his improved Con modifier to determine the duration. A bestial champion may use this ability one additional time per day per four levels (2/day at 5th, 3/day at 9th, 4/day at 13th, and 5/day at 17th). A bestial champion may not use this ability to improve more than one ability at once (but see secondary bestial aspect, below).
Bestial Charm (Sp): At 2nd level, a bestial champion can use charm animal 1/day as a spell-like ability. A bestial champion may speak with any animal he has charmed as if using speak with animals. A bestial champion can use this ability one additional time per day for every two levels.
Bestial Sway (Sp): At 3rd level, a bestial champion can use suggestion 1/day against any creature of the animal, magical beast, or vermin type. The creature need not be able to understand the bestial champion, and this can even affect creatures that are normally immune to suggestion. A bestial champion can use this ability one additional time per day per four levels (2/day at 7th, 3/day at 11th, 4/day at 15th, and 5/day at 19th).
Bestial Dominion (Sp): At 5th level, a bestial champion can use dominate animal 1/day as a spell-like ability. A bestial champion may use this ability one additional time per day per six levels (2/day at 11th and 3/day at 17th).
True Companion: At 6th level, a bestial champion gains the Leadership feat, but only for the purpose of acquiring a cohort of the animal, dragon, magical beast, and vermin type. In addition, he may only acquire followers of the animal, magical beast, or vermin type. If the bestial champion wishes, this creature replaces his animal companion and henceforth is always of the highest possible level or advancement.
Greater Bestial Aspect (Ex): At 8th level, a bestial champion's bestial aspect bonus improves to +4.
Summon Beasts (Sp): At 10th level, a bestial champion may use summon nature's ally V 1/day, but only to summon animals, magical beasts, or vermin.
Imbue With Bestial Aspect (Su): At 12th level, a bestial champion may use a standard action to grant one ally within 30 feet the benefit of his bestial aspect for a number of rounds equal to his Charisma modifier. This uses up one use of his bestial aspect for the day.
Summon Greater Beasts (Sp): At 14th level, a bestial champion may use summon nature's ally VII 1/day, but only to summon animals, magical beasts, or vermin.
Secondary Bestial Aspect (Ex): At 16th level, a bestial champion may use his bestial aspect to improve two physical ability scores, but only when he gains the benefit himself.
Call Bestial Followers (Su): At 18th level, a bestial champion may summon any of his followers (those gained through his True Companion ability) to his side instantly a number of times per day equal to his Charisma modifier. He may summon a number of followers whose hit dice are equal to or less than his bestial champion level.
Perfect Bestial Aspect (Ex): At 20th level, a bestial champion gains a +6 to all three physical ability scores when using his bestial aspect and the duration is for twice his newly improved Con modifier.[/sblock]
