Dragon adapt, also says the meta-breath feats are a good choice for the character.
Actually this is an often times over argued theme I've seen in the threads. Considering that the Meta-breaths are special breath effects expressed in rounds (ex: Recover Breath lowers the recovery rate by 1 round, meaning you breath sooner), and so are argued that you need breath weapons that are expressed in rounds as well. Since Dragonfire Adepts (I'm guessing that's what you meant) are capable of breathing every round (their special effects just replace the normal fire, and can't be used twice in a row) so the classes breath weapon is a no go. So most people argue that if the person takes the Dragonborn of Bahamut template's Heart aspiration (gain breath weapon that grows in power, and range as you gain HD) works since you need to wait 1d4 rounds.
So for the question at hand, yes there are some feats that you 'technically' could use like Awaken Frightful Presence, but then there are feats that are argued that you can't. Ones that generally stat 'Age Categories' for example are the big ones that people try to state they can get, stating a little table presented in the Races of the Dragon book for Kobolds qualifies them for the Categories despite it being for flavor. Personally, as a Dm I would allow at least Awaken Frightful Presence (especially since it states the following...)
Quote:
You gain frightful presence.
Prerequisites: Cha 11, dragon type.
Benefit: You gain the frightful presence special ability with a radius in feet equal to 5 × 1/2 your racial Hit Dice. The ability takes effect automatically whenever you attack, charge, or fly overhead. Creatures within the radius are subject to the effect if they can see you and have fewer Hit Dice than your racial Hit Dice. A potentially affected creature that succeeds on a Will save (DC 10 + 1/2 your racial HD + your Cha modifier) remains immune to your frightful presence for 24 hours. On a failure, creatures with 4 or fewer Hit Dice becomepanicked for 4d6 rounds and those with 5 or more Hit Dice become shaken for 4d6 rounds. Dragons ignore the frightfulpresence of other dragons.Special: If you have both this feat and you have (or later gain) the frightful presence ability, your frightful
presence radius either increases by 50% or increases to 5 feet × 1/2 your racial Hit Dice, whichever figure is higher. The save DC against your frightful presence also increases by 2.
Meaning that you have a radius equal to technically 2.5ft (5x1/2 racial hd [kobolds have 1 hd]= 5x1/2= 2.5), you would be doing better with the Frightful Presence feat.
Quote:
Prerequisite: Cha 15, Intimidate 9 ranks.
Benefit: You gain the use of the frightful presence ability. Whenever you attack or charge, all opponents within a radius of 30 feet who have fewer levels or Hit Dice than you become shaken for a number of rounds equal to 1d6 + your Cha modifier. The effect is negated by a Will save (DC 10 + 1/2 your character level + your Cha modifier).
A successful save indicates that the opponent is immune to your frightful presence for 24 hours. This ability can't affect creatures with an Intelligence of 3 or lower, nor does it have any effect on dragons.
30ft, same number for the save, along with the fact it activates whenever you attack/charge/(technically it should include fly over) your opponent, just like the earlier mentioned feat. Course you have to wait till you meet the requirements, but at least you have a bigger range.
But of course, that's just how I read it.... For more info, here is at least a few threads I could find during my times playing as kobolds that could help enlighten you in what I mean about how people argue...
